WILLIAM ,A. COCKE, OF CARTERSVILLE, VIRGINIA.

S'IU'MP-PULLER.

To all whom it may concern:

Be it known'that 1, WILLIAM A. Coons, a citizen of the United States,residing at Cartersville, in the county of Cumberland and State ofVirginia, have invented certain new and useful Improvements inStump-Pullers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in stump pullers.

The object of this invention is to provide a machine equipped with novelmeans'for pulling stumps, roots or the like from the ground and also maybe used as a lifting machine for raising heavy weights such as lumber,iron or the like and this machine is equipped with a mechanism wherebystumps may be pulled up or other materials lifted in a quick andreliable manner.

A still further object of this invention is to provide a stump pullingmachine with a frame and having novel power applying mechanism arrangedto be secured to the shaft for rotating the drums.

A still further object of this invention is to provide drums with novelmeans whereby the drums may be rotated in either direction.

A still further object of this invention is to provide a device of thischaracter, which will be simple, practical and comparatively inexpensivein construction and one that can be manufactured and sold at a low cost.

With these and other objects in view, the invention consists in thenovel combination and arrangement of parts hereinafter more fullydescribed and set forth in the claims hereto appended.

Application filed April 20, 1917. Serial No. 163,437.

Fig. 7 is a fragmentary detail sectional view of the shaft and gear,

Fig. 8 is a fragmentary sectional. view illustrating the manner in whichthe movable roller is swivelly connected by one end in the frame.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

Referring to the drawings, the numeral 1 designates a rectangular framein its entirety. The frame comprises a bottom rail 2, vertical end rails3 and a tcp rail 4-.

The top rail f is provided adjacent one end with a longitudinallyextending slot 5 which communicates with and extends outwardly throughthe opening 6 arranged therein.

The opening 6 is adapted to receive the screw threads 7 of the shaft 8,a handle formed on the outer end of the shaft 8 to facilitate the movingof the shaft inwardly or outwardly in the slot 5 in the top rail of theframe. The inner end of the shaft 8 is enlarged as at 10 and has securedthereto a bearing collar 11 the purpose of which will be hereinaftermore fully described.

A rectangular closure plate 12 is secured over the slot 5 in the toprail 4 by suitable fastening means 13 as illustrated in Fig. 4 of thedrawings.

A relatively stationary drum 14 is journaled in the bottom and top railsof the frame adjacent one end thereof and this drum carries a gear 15which is located in wardly beyond and in close proximity to the top rail4 as illustrated.

A relatively movable drum 16 is journaled in the bottom rail as at 17and has its opposite ends journaled in the bearing 11 on the inner endof the shaft 8 as illustrated thus facilitating the adjustment of therelatively movable drum with relation to the stationary drum,

A pair of gears 18 of different diameters are secured to the relativelymovable drum adjacent the upper end thereof and in close proximity tothe inner face of the top rail 4: as illustrated.

A shaft 19 is rotatably mounted in the top and bottom rails centrallythereof and has its upper end projecting upwardly beyond the outersurface of the top rail as at 20 which terminates in-a reduced squaredshank 21 which is adapted to receive an operating handle 2:2 thereon.

The gear 24 when rotated intone direction is adapted to mesh with thegears and 18 of the drums 14 and 16 and when moved upward on the shaft19 and the drum 16 is moved inwardly it is adapted to mesh with the gear18 and gear 15 to cause rotation of the drum in different direction uponreverse rotation of the crank handle 22. p

The lower end of the relatively movable drum is provided with a trunnionwhich terminates in a ball 26 which ball is adapted torest in a bearinghousing 27 removably secured to the exterior of the bottom rail 2.

' The inner surface of the bearing housing is provided with an inwardlytapering recess 28 which is adapted to receive the ball and the bottomrail is provided with an inwardly tapering opening which alines with therecess 28 to receive the ball 26 therein so as to permit pivotalmovement of the relatively movable drum therein so as to facilitate themoving of the movable drum with relation to the stationary drum.

The drum 14 carrying the gear 15 and the drum 16 carrying the gears 18and 18 are arranged to have engagement with one another through themedium of the gear 24 which is carried by the shaft 19. The gear 24 whenrotated downwardly on the shaft 19 engages the gear wheel 18 of the drum16 and the gear 15 of the drum 14 and it is to be understood that thegear 18 is of. a larger diameter than the gear 15 carried by the drum 14thereby upon rotation in one direction the drum 14 will make a greaterspeed and have more revolutions than the drum 16. hen the shaft isturned in the reverse direction the gear 24 moves upwardly, and themovable drum is moved inwardly thus meshing the gear 18' withthe gear 24and the gear '15 whereby upon reverse rotation of the shaft the gear 18being of a'smaller diameter than the gear 15 the drum 16 makes morerevolutions than the drum '14, the purpose of which will be hereinaftermore fully described.

A cable 29 has one end removably secured to the drum 14 as at 30 and itsopposite 'end is wound about the drum 16 as at 31 and has a portiondepending from the drumor extending laterally from the drums as at 32whichis adapted to'receive'a pulley wheel 33 to "which is journaled aU-shaped yoke 34 having connected to its web portion and eye 35 aflexible cable 36 which isad'apted to be wound about a stump orplaced'upon material which is moved upon rotation of the drums throughthe medium of the shaft '19 and "crank 22;

It can be understood that the drums Can be used in either a horizontalor vertical position depending upon the manner in which the device is tobe used for moving. W'Vhen it is used as a stump puller, the drums canbe set up in a vertical position and the cable 32 movedlaterallytherefrom and connected to the stump which is designated PA inthe drawings.

Vhen it is connected up with the stump in the manner described, thestump willbe easily and quickly lifted, due toithe fact that there iscomparatively no slack-in the .cable as a constant pull is obtained byone drum being rotated faster than the opposite drum.

Now referring to Figs. and '6, wherein there is shown a power operatingmechanism which facilitates the rotating, of the drum, by any suitablepower source, there is illus' trated a frame 1, in which is a drum14'and a movable roller drum 16. But insteadgof rotating the drums withthe crank handle 22, there is secured tothe upper end of the shaft 19,a, gear 37 which is arranged on the squared portion of the shaft forrotation therewith.

The wheel 3-7 is a worm wheelora worm gear and is adapted to meshwiththe worms 38 located on oppositefsides ,thereof and swivelly'connectedas at 39 tothesupporting plate 40 which is secured toz-the toprail 4 .bysuitable brackets 41. Theopposite ends of the worms 38 arepivotally-secured as a-t 42 to the arms of the Y-shapedlever' 43. AU-shaped frame 44isfsecured;by the' ends of its legs to theioppositesideiedges .of'the'top rail 4 as at 45 and its web isprovidedioirits upper side with a plurality OfSPfl-CGClLilOtChQS 46 inwhich is adapt'ed' to'be fittedt'he lug 47 carried by the stem of theY-shapedlever 43; A spring 48 is securedas at-49 to the under side ofthestem of the lever 43' andzis adapt ed "to engagewthe web portion44=of .theU- shaped member to normally retainzthe lug 47 on thestemof'the lever inone of the notches or recesses '46.

The supporting member .40 has journaled centrally therein a shaft '50"whichcarries the gear wheel centrallyof its endsdesig" nated 51, apulley 52 is secured tol'the outer end of the shaft 5O whichisadapted'to re-' ceive a driving belt 53' :whichi'facilitates therotating of theshaft and gear 51, a pair-0f smaller gears 53 arerotatably mounted on the member'4O2on opposite sides of thegear 51 andare adapted'toamesh therewitlr'and they have a sha'ft extending throughand pivotally connected to the inner and lower ends'of thew'o'rms38 asat41.

When it is desired touse'the power driven device with my improved stumpIpuller. the handle 54 is grabbed and the stem :of the Y-shaped member43 is moved either to the right or left to turn a respective worm intoengagement with the gear 37 whereby upon rotation of the shaft throughthe medium of the pulley 52 the drums will be either rotated in theright or left direction.
